VEMS Ign. Table, how much advance ?

[GazzaG60]

heat is ok to an extent. bad afr will not help. look to the weakest fueled area also. the one farest from the tb usually. it gets the most air.

[th.b.w.]

Hi,

is there an possibility to adjust ign. timing cyl. selektiv with VEMS to decrease the advance a little bit ?
Let say 2-3° ???

After rebuild the valve i can't see where the steeldrop is going to..
The Turbo hotside is o.k., no damage..

I will only change the Valve and it is o.k.

Tomorrow will rebuild the pistons and see the ringlands...

You want to delay the ignition on just one cylinder?
You need one of the latest firmwares like 1.1.81.

Then you have it under Base Setup -> Cyl seperated Spark delay

Hy,

the piston land from cyl 4 is to much damaged, i change them....


@Erikk
This sounds fine, than i will change to 1.1.81 and see how it works......Thank you

how does spark delay work? does it mean that the advance can be reeuced selectivwlly on a cylinder so as to reduce the chance of knock?

Hi,

i seen at the new Vemstune 1.1.81 the inj. angle curve, what angle setup must i use ???

You dont have to use it, put 720 in all cells do disable it - if you want to try, then its test'n'tune as they say
